Oil saving attachment for wells



1931- E. G. REIGHNER OIL SAVING ATTACHMENT FOR WELLS Filed Nov. "7, 1950 Patented Dec. 15, 1931 UNITED, STATES EDWARD e. REIG-H'NER, or HAYNES'VILLE, LOUISIANA OIL SAVING ATTACHMENT FOR WELLS Application filed November 7, 1930. Serial No. 494,142.

This invention relates to an attachment for use in connection with oil wells whereby oil which is ordinarily wasted while tubing is being pulled for repairs or the like will be saved a and returned to the well or to any suitable container provided therefor.

\Vhen it is found necessary to pull the tubing of a well for the purpose of making repairs, it is the general practice to elevate the to tubing and when each length of 60 or 80 feet is broken out any oil that might have been trapped therein has been wasted through the lack of suitable means for gathering it.

The present invention provides a simple and eflicient device which can be applied readily to the tubing directly at the point where the separation is to be made so that oil drained from the tubing thereabove can be directed back to the well or to any suitable container.

With the foregoing and other objects in view which will appear asthe description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made Within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings:

Figure 1 is an elevation showing the attachment applied to a well casing and to a section" of tubing for the purpose of saving oil which would otherwise be wasted.

Figure 2 is a longitudinal section through the attachment.

40 Figure 3 is a section on line 3-3, Figure 2.

Referring to the figures by characters of reference, 1 and 2 designate elongated arcuate plates forming sleeve sections, these plates being hingedly connected as at 3 so that they can be swung apart or together.

For the purpose of drawing the sections toward each other and fastening them a lever 4 can be hingedly connected to one section.

This lever carries a link 5 adapted to engage 9 a lug 6 on the other section. By placing the link in engagement with the lug and swinging the lever back against section 1 the two sections can be drawn together and the link moved past its dead center so that the parts will remain in tightened position.

An outlet spout 7'-is carried b and opens through the sleeve section 2 and 'tted snugly against the inner surface of each sleeve is a lining 8 formed preferably of soft rubber or a compressible rubber composition. The upper portion of this lining is thicker than the lower portion so as to provide an interior shoulder 9 located above the level of the spout 7. I i y V In practice the tubing T is withdrawn a desired distance from the well casing C until. its coupling T has been brought to position above the casing. The sleeve formed of the sections 1 and 2is then placed around the coupling T and the section T thereabove and when said section is separated from the coupling T as shown by broken lines in Figure 2, the sleeve is tightly clamped about these parts by shifting lever 4.- Thus liquid reeased from the section T will be free to flow into the space below the shoulder 9 and thence to the spout 7. v

Before the liquid is released as heretofore" explained, tube 10 is coupled to the spout 7 and can also be coupled to the casing C. If preferred, however, this tubing can be ex tended to a container of suitable proportions. In either event the liquid delivered to the spout 7 will be conducted by the'tube 10 to the point where it is to be retained.

Importance is attached to the fact that the sleeve can be quickly clamped upon the parts and when so clamped will act as a tight coupling between the tube 10 and the separated parts T and T. p

This is due to the fact that, the innersur: face of the lining is cylindrical for the greater portion of its length, The sleeve can have a considerable longitudinal movement relative to the coupling T without producing a leak at said joint. As the upper end of the-lining is thickened to compensate for differences be- .tweenthe diameters ofthe tube T and cow pling T, the sleeve when closed tightl inposition will bind with equal pressure. 0th

on [the tube and coupling, Consequently there is no danger of a blow-out of oil at either end of the sleeve.

What is claimed is a An oil saver including hingedly connected 5 sections providing a split sleeveof uniform diameter, a thick tubular lining of resilient material extending within and throughout the length of the sleeve, said lining being split longitudinally and separable, the in ternal diameterof the lining at one end being greater than the internal diameter of the remainder of the lining thereb to provide an annular oil receiving cham er within the lining when applied we pipe and coupling 15 of different diameters, a drain opening into the lining at a point of greatest internal diameter, and means on the split sleeve for closing the sleeve and binding the lining on 20 said pipe and coupling without contracting the said chamber to an undesirable extent or disturbing its communication with ;the drain. 7 In testimony that I claim the foreging as 5 my own, I have hereto aflixed my signature.
